BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a gas powered hand gun having a gascartridge retaining device. The retaining device comprises a quickrelease and reloading camshaft mechanism for the speedy power cartridgereplacement.

2. Description of Relative Prior Art

Conventional CO2 cartridge is mounted in an air gun which has acartridge retaining device to lock the cartridge inside the gun forpellets shooting.

Referring to FIG. 1, an air gun 1 a has a hand grip 11 a having acartridge storing groove 12 a. A grip cover 3 a is used to cover thecartridge storing groove 12 a, a CO2 cartridge 4 a is loaded inside thegroove 12 a. A conventional cartridge locking device 2 a is disposed atthe bottom of the hand grip 11 a. The locking device 2 a comprises atightening screw 21 a and a locking pad 22 a. The screw 21 a is turnedinward into the groove 12 a inside the hand grip 11 a. Therefore,turning the screw 21 a is to tighten and raise the pad 22 a to lock thecartridge 12 a in place for shooting.

After empty the gas inside the CO2 cartridge from shooting, the steps ofreplacing a CO2 gas cartridge 4 a is first to remove the hand grip cover3 a, loosen the tightening screw 21 a to lower the locking pad 22 a,remove the cartridge 4 a to empty the groove 12 a, reload a new CO2cartridge 4 a in place, tighten the screw 21 a, and then closing thegrip cover 3 a. Therefore, the replacing steps are very complex and verytime consumption.

As discussed above, the prior art has a lot of drawbacks that could beimproved upon. The present invention aims to resolve these drawbacks andgreatly simplify the steps and at meantime reducing the time needed forthe cartridge replacement action, consequently speed up the cartridgereplacement to maximize the pleasure of shooting.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a power gun to have aquick release cartridge retaining device for the gas power cartridge.The replacement of the gas cartridge can be accomplished by one singleaction of open and close the hand grip with a gas cartridge retainingdevice. Swivel the hand grip open to loose the used empty cartridge,replace a new cartridge and lock it in place for immediate shooting byclosing a camshaft lever of the gas cartridge retaining device. Moreoverthere is no more protruding tightening screw at the bottom of the handgrip, the shape and appearance of the gun is more resemble to real gunsto make them more attractive to the consumers.

For achieving the above object, the present invention equip with acartridge retaining device comprising: a hand grip having a cartridgestoring groove; and a gas cartridge retaining device having a pivotedcamshaft lever and a retaining pad is disposed at the bottom of the handgrip. Moreover, the camshaft lever is adjunct to the grip cover.

Numerous additional features, benefits and details of the presentinvention are elaborated in the detail description listed below.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Refer to FIGS. 2 and 3; the present invention includes a gun device 1and a gas cartridge retaining device 2, and a grip cover 3. The gundevice 1 has a hand grip 2, and the hand grip 2 has a cartridge storinggroove 12 for receiving a gas cartridge 4. The gas cartridge retainingdevice 2 is disposed at the bottom of the hand grip 2. The gas cartridgeretaining device 2 includes a shell 21, a camshaft lever 22, and apushing portion 23. The shell 21 is fixed on the bottom of the hand grip2. Pull up the camshaft lever 22 for pushing the pushing portion 23, andthan the gas cartridge 4 will be retained by the pushing portion 23 andthe top surface of the cartridge storing groove 12. The grip cover 3 isfixed with the side of the camshaft lever 22, and grip covers thereceiving portion 12.

Refer to FIGS. 4 and 5; the details of the gas cartridge retainingdevice 2 are described below.

The shell 21 is a tube shape. The bottom of the shell 21 has two tabs211 extending thereof. The top of the camshaft lever 22 is pilotedbetween the tabs 221. The pushing portion 23 is disposed slidably in theshell 22, and the top of the pushing portion 21 is exported in thecartridge storing groove 12. In the other embodiment, the shell 21 isintegrated with the hand grip 2.

The pushing porting 23 includes a locking pad 231 and a column 232. Thelocking pad 231 is disposed on the top of the column 232, and the shapeof the top of the locking pad 231 can be fitting with the shape of thebottom of the gas cartridge 4. The column 232 is disposed slidably inthe shell 21. The column 232 has a groove 233. A post 234 penetratesthrough the shell 21 and the groove 233 for limit the movement of thecolumn 232 in the shell 21.

The camshaft lever 22 has a rib 221 and an arm 222. The rib 221 and thearm 222 extend perpendicularly from the camshaft lever 22 in the samedirection. Pull up the arm 222 to a fasten position (as shown in FIG.5), and the rib 221 will push the bottom of the column 232 upwardly.Pull open the arm 222 to a releasing position (as shown in FIG. 6). Therib 221 will not push the bottom of the column 232, and the pushingportion 23 can be moveable.

In this embodiment, the rib 221 has a recess 223, and a wheel 235 ispiloted on the bottom of the column 232. When the rib 221 is pushing thebottom of the column 232, and the rib will be sliding along wheel 235.Therefore, the rotation of the camshaft lever 22 can be smoothly.Moreover, when the arm 222 to a fasten position, the wheel 235 will befall into the recess 223. Therefore, the position of the camshaft lever22 can be fixed.

Refer to FIG. 6, the grip cover 3 is fixed with the arm 222 and pivotedwith the tab 211 of the shell 21 and the camshaft lever 22. The gascartridge 4 is disposed in the cartridge storing groove 12. When closethe grip cover 3 for covering over the cartridge storing groove 12, thegas cartridge retaining device 2 push the gas cartridge 4 upwardly, andthe gas cartridge 4 is held by the gas cartridge retaining device 2 andthe top surface of the cartridge storing groove 12. When open the gripcover 3, the pushing portion 23 is moveable and releases the space fortaking off the gas cartridge 4. In the other embodiment, the grip cover3 is integrated with the camshaft lever 22.
